A method and apparatus for performing a data strobe-to-data delay calibration is disclosed. In one embodiment, a data strobe signal, along with data, is conveyed from a memory controller to a memory. An initial delay calibration procedure may be performed to align the data and the data strobe signals at the memory, with subsequent calibrations performed there between in order to compensate for changes due to various factors such as voltage and temperature. In the calibrations performed between the delay calibration procedures, a calibrated delay value may be multiplied by a first scaling factor and a second scaling factor to generate a scaled code. A DLL configured to convey the data strobe signal may then be programmed based on this code.
